Application filed December 4, 1913. Serial No. 804,719.

To all whom it may concern:

Be it known that 1, PETER CODINA, a subject of the King of Spain, residing: at Hoboken, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Cork-Cutting Machines, of which the following is a full, clear, and exact description.

The object of this invention is to provide a machine by means of which corks or stoppers of various kinds and sizes, and for various purposes, may be cut accurately, with great rapidity, and with a utilization of the bark without waste.

The invention comprises a cork cutting machine in which the bark in strips of a width equal to the length of the cork, is exposed to the cutting action of a punch or cutter and intermittently fed into position to be so acted upon by the punch or cutter as the latter is caused to be both reciprocated and rotated; and the invention also includes a strip trimming mechanism operative while the strip is passing through the machine to render available the remaining good parts of the punched strip for the production of disk and such like stopper or closure elements, all as I will probeed now to explain and finally claim.

In the accompanying drawing illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view of a machine embodying the invention. Fig. 2 is a side elevation looking in the direction of the arrow, Fig. 1, with a part of one of the bearings for the mandrel broken away. Fig. 3 is a front elevation. Fig. 4; is a cross-section on a larger scale taken on the line A B, Fig. Fig. 5 is a cross-section taken on line C I), Fig. 2, and looking toward the right, and Fig. 6 is a cross-section on the line E F, Fig. 2, looking toward the left, showing the feed Fig. 7 is a longitudinal section of the, punch or cutter and its mandrel, showing the ejector in elevation. Fig. 8 is a face view of the combined work-guide and punch-block. Fig. 9 is a perspective view illustrating some of the operations on the cork bark that are within the capability of the machine.

Without thereby limiting the invention or its adaptability, I will proceed to describe the same as illustrated in the drawings.

1 may represent a bed-plate, mounted mounted a shaft 4 provided with fastand loose pulleys 5 and 6, in connection with which is any ordinary bolt shifter 7 operated by a lever 8 pivoted beneath the bed: plate. on this shaft 4 is also mounted a cam 9 for impartinga reciprocating motion to the punch or cutter mandrel as presently described; and also on this shaft is mounted-'- a crank-disk 10 to operate the 'main feed shaft as presently described.

As shown more in detail in Fig. 7, the punch or cutter mandrel or shaft 11 is hollow or tubular, and it is providedin tiny suitable way with the tubular punch or cutter 12 which acts upon the strip of bark to punch out the corks. Within this hollow pusher 1,3 which acts upon a movable rod or tially the internal diameter of the punch The rod 13is adjustably fixed in a standard 16, as by means of a set-screw 17. The mandrel 11 is mounted in the bearings 18 and 19, erected on the bed-plate 1, and is means,-for imparting to it an independent with a pin collar 21 loose thereon'and held.

22. and this pin collar-is engaged by a fork 23 shdmglymounted m a lever 24 p voted.

a roller connection 27 with the cam 9 so as to impart a longitudinal reciprocation to the mandrel as the cam is rotated.

The bearings 18 and .19 receive a verticaliy adjustable cross-head 28 mounted upon an adjusting screw 29, which in turn is mounted in the bed-plate, so that said cross-head may be moved vertically up and down in the bearings. This cross-head carries the bearingblocks 30. and in those bearing-blocks is mounted the t'cedshaft 31, saidi'eedl-shaft being located immediately below and in ertical alinement with the mandrel 11 and parallel therewith. At one end of the feed, shaft 31 .is a ratchet wheel 32 keyed to said shaft by means of a key-33 mounted in a longitudinal key-way or seat 34 in said shaft, sothat said shaft may be adjusted longi tudinally in its bearings and in the ratchet .upon suitable legs or frames 2. Erectcd on Y the bed plate are bearing-pieces 3 in which is mandrelis arranged a stationary rod orejcctor 14. having the head 15 of substan-.-'

provided with a pulley 20, or any other rapid rotation; and said shaft is provided;

in place lengthwise of the shaft by collags at .25 to a bracket 26 extending from one side of the bed-plate, and said lever 24: has;

- m sses conveniently fastened to the head as shown in Figs. 5 and 6, and this shield-is provided with a hole 88 in the path of travel of the punch and through which the punch passes in cutting the cork. This shield may be provided with the vertically disposed friction roller 89 to relieve friction, of the" they are ejected from the punch.

In order to keep the punch clean and oiled, a swab 92 may be mounted upon an arm 93 fixed to the bearing 18.

' The machine as so far described is adapted to act upon a strip of cork bark cut to a width equal to the length of cork desired. Such a strip is placed in the work-holder with its outside or back uppermost. Power being applied to the machine, the punch mandrel is given a rotary and longitudinally reciprocating motion, and the punch bores through the work and is then retracted, and on the back movement the ejector is brought into operation to eject the cut cork, and then the feed wheels become active to feed the work forward for the next cut. The

feed of the work is, of course, essentially a friction feed, and such feed is arrested dur V ing the moment of time'the cutter is passing into and out of the work by means of the intermittent ratchet feed previously described. The rollers a8 and 81 are practically work supports for supporting the work after it leaves the work-holder, andat the time it is being punched, and the upper roller 81 is of sufiicient weight to act as a hold-down or presser for the work.

I have shown the headed ejector 1415 as separate from the actuating rod.13, but in practice the suction caused by the rapidity of motion, prevent the dislodgment of the device from -the punch.

lVhere the stock or bark is of greater thickness than suificient to form the desired size of cork, and yet contains enough valuable cork for the manufacture of the disks that are largely used in bottle stoppers of the cap variety, the stock may-be prepared for the subsequent cutting of such cork disks by trimming oii the outer rough portion or back, as indicated in Fig. 9, thereby leaving a thickness suff cient to form such cork disks. For the purpose of thus preparing thestoek while it is being punched for cylindrical corks, Tprovide a rotary circular cutter 94, such as a knife or saw, mounted on a vertical shaft 95, which is'driven in any suitable manner, as by means of a .belt

96 engaging a pulley 97 on the shaft 95 and a pulley 98 on a shaft 99 erected on the bearing 3, for example, and driven by bevel gearing 100 from the shaft 4. Any suitable belt tightener, automatic or otherwise, indicatedat 101, may be used to-keep the belt taut. The rotary cutter 94 may be mounted upon its shaft 95 to turn therewith, in any suitable way, by which it may be adjusted with relation to the punch or cutter 12 to out the sto ck to the desired level outside of the spaces, formed by cutting out the corks, and I have shown it so adjustable by a screwthread arrangement comprising the screwthread 102onfthe shaft, and the ad justing nuts 103 and 104.

A stock or work support 105 is arranged opposite the cutter to take the thrust of the cutter, and this support may be mounted upon an arm 106 adjustably secured to the stand 83, so as to be capable of being adj usted correspondingly with the table 70.'

The shaft 95 may be stepped in an arm 107, projecting from the base of the stand 83, and this stand may be adjusted in ways 108 on the bed-plate by means of a suitable adjusting screw 109. By this adjustment also, the upper roller 81 may be kept in alincment with the lower roller 48.

Variationsin the details of construction and arrangement of parts are within the principle of the invention, and the scope of the claims hereinafter made.

-What I claim is 1. In a cork cutting machine, the combination of a main shaft, a feedshaft, con nections between said main shaft and feed shaft to intermittently .rotate said. feed shaft, a mandrel, a cutter carried by said mandrel means to reci rocate said mandrel lengthwise, independent means to rotate said mandrel, a feed roller mounted on and turning with the feedshaft and. adapted to engage the stock on its undersideiin line with said mandrel and cutter, a comple mental gravity feed roller adapted to engage the stock on its upper side in line with the mandrel and cutter, feed wheels arranged at right angles to the axes of the feed rollers and adapted to engage one side of the work.

or stock in advance of the feed rollers, a work or stock supporting mechanism adapted to support the work orstcck against the thrust of the mandrel and the action of said feed wheels, and means to drive the feed wheels from the feed shaft.
